I already have a simple water pressure gauge (something like this) that I can attach to a standard hose bib in my backyard. However, that will only tell me the pressure in the “house system”. I believe my existing irrigation lines have been tapped before the house water pressure regulator comes into play.
Is there some adapter I could buy to put on an existing typical pop up sprinkler to figure out the pressure in the irrigation system?
Thanks - I did do a search but did not find any specific post that talks about how to measure the pressure in the irrigation system. Hopefully someone out there has a relatively simple trick that can be used…
Hunter makes one that works on any male thread sprinklers (basically anything but Toro I think)…You would remove your nozzle, put this in it’s place, and put the nozzle on top of the gauge. Tests pressure at the individual sprinkler. Might do a few to try and get an average because length of run and direction changes can reduce pressure.
You are right. But the MP gauge fits female threaded heads such as Irritrol, Hunter, Rain Bird and and Weathermatic. I have several of these gauges and use them all week. For male thread Toro heads you are out of luck, unless you rig up a homemade gauge checker. Sprinkler Warehouse sells the plastic adapter. But you can get the complete MP Gauge for $25.00. Contractor price for a Merrill pressure gauge is $8 here. But dont know much the retail price might be.
I tried to unscrew the hose bib adapter from my el-cheapo gauge (the link I had shared earlier), but it wouldn’t budge, and I was afraid it would damage the joint/connector at the gauge itself, so I aborted that attempt. I wonder why there is such a discrepancy in prices for these two different applications. Anyway, I guess it might be a good idea to have the right tool anyway.
